The argument escalated into gunfire when the husband followed Barreca to her car, where she got her Ruger .380-caliber handgun and he slapped and pushed her, the report said.

The husband, whom police did not identify, called 911. Police found that Barreca also had been shot, the report said. She had a gunshot wound in her right thigh, but the injury was not life threatening, police said.

The shot in the husband’s back indicated he was fleeing rather than attacking, police said

Barreca “showed no signs of emotion or remorse” and did not ask about her husband’s condition, the report said.
